FIGS. 6 and 7 show setting 422 screens for a tethering distribution control method, according to an embodiment of the present invention. As described in herein, the term “leecher” refers to a device that connects to a device of providing tethering to use data.

Referring to FIGS. 1 and 4, in a tethering distribution control method, according to an embodiment of the present invention, at least one leecher to which data is to be tethered is detected, in step 1110. The controller 110 of the mobile device 100 may detect the at least one leecher to which data is to be tethered.

The mobile device 100 may provide a tethering function. The tethering function enables the mobile device 100 to function as a mobile hotspot so that at least one leecher connected to the mobile device 100 can use a network communication service such as, for example, the Internet. The mobile device 100 may be a host device that functions as a mobile hotspot with respect to the at least one leecher. Accordingly, the mobile device 100 functions as a portable WAP to route data to the at least one leecher. For example, the at least one leecher may be an electronic device, such as, for example, a smart phone, a tablet computer, and a laptop computer. Accordingly, the at least one leecher may use a network service such as, for example, the Internet, using the tethering function of the mobile device 100.

The controller 110 of the mobile device 100 may activate tethering with respect to the at least one leecher. For example, as illustrated of FIG. 6, “ON” and “OFF” icons 414 for activating and deactivating tethering may be displayed on the display unit 190. Tethering may be activated when a user inputs a predetermined password. The controller 110 of the mobile device 100 may open or close tethering with respect to each of the at least one leecher.

The controller 110 of the mobile device 100 may detect at least one leecher to which data is to be tethered. Referring to FIG. 5A, the mobile device 100 may detect one or more leechers 310 to 350. Then, the mobile device 100 may connect to the leechers 310 to 350 through communication. Mobile device 100 may have limit of data 200 that is to be tethered to connect all leecher to the mobile device 100. Each leecher may be tethered data by the mobile device 100, and the mobile device 100 may adjust the amounts of tethered data corresponding to the leecher. For example, mobile device 100 may adjust amounts 312 to 352 of data that are to be tethered to correspond to the respective first to fifth leechers 310 to 350, to 700 MB, 200 MB, 1 GB, 500 MB, and 1 GB, respectively. For example, the mobile device 100 may connect to the leechers 310 to 350 through USB cables, Wi-Fi, or Bluetooth. Accordingly, the controller 110 of the mobile device 100 may detect one or more leechers 310 to 350 to which data is to be tethered through the communication. For example, the controller 110 may detect the first, second, and third leechers 310, 320, and 330. Then, the controller 110 may display information notifying that the three leechers 310, 320, and 330 have been detected on the display unit 190. Also, the controller 110 may display information 510, 520, and 530 about the first, second, and third leechers 310, 320, and 330 on the display unit 190, as illustrated in FIG. 6.

Referring again to FIG. 4, data that is to be tethered to the at least one leecher may be controlled, in step 1120. The controller 110 of the mobile device 100 may control data that is to be tethered to the at least one leecher. Data usage may be controlled by adjusting an amount of data that is to be tethered to correspond to each of the at least one leecher.

For example, the mobile device 100 may set a default data corresponding to the at least one of the leecher 620. That is, the mobile device (100) may adjust leecher 624 or may not adjust leecher 626 of default data that is set at 200 MB 622.

Referring again to FIG. 5B, the controller 110 of the mobile device 100 may control data that is to be tethered to the leechers 310 to 350. Specifically, the controller 110 may control data usage by adjusting an amount of data that is to be tethered to correspond to each of the leechers 310 to 350. For example, as illustrated in FIG. 5B, if the at least one leecher is the first to fifth Leechers 310 to 350, the controller 110 may adjust amounts 312 to 352 of data that are to be tethered to correspond to the respective first to fifth leechers 310 to 350, to 700 MB, 200 MB, 1 GB, 500 MB, and 1 GB, respectively. In this way, in a tethering distribution control method, according to an embodiment of the present invention, an amount of data that is to be tethered to correspond to each of at least one leecher can be controlled.

Controlling data usage may include at least one of detecting an amount of data tethered during at least one session, detecting a use purpose of tethered data, adjusting a maximum data limit that can be tethered to each of at least one leecher, monitoring an amount of data tethered to each of at least one leecher in real time to re-adjust the maximum data limit, stopping tethering with respect to each of at least one leecher, and accepting a request for tethering additional data exceeding the maximum data limit from at least one leecher.

For example, controlling data usage may include detecting an amount of data tethered during at least one session. For example, the controller 110 of the mobile device 100 may detect an amount of data tethered during at least one session to adjust an amount of data that is to be tethered to correspond to each of at least one leecher. The at least one session may be a time period for which tethering starts and then terminates. For example, data of 20 MB may be tethered during a first session for which tethering of a first leecher starts and then terminates. In this case, if 20 MB is more than a predetermined amount of data, the controller 110 may decrease or increase an amount of data that is to be tethered. Accordingly, the controller 110 may detect an amount of data tethered during at least one session, and decrease or increase an amount of data that is to be tethered to correspond to each of at least one leecher in consideration of the detected amount of data. In addition, the controller 110 may display the amount of data tethered during the at least one session on the display unit 190.

For example, as illustrated in FIG. 6, the controller 110 may display an amount of data tethered during at least one session corresponding to a first leecher as “92 MB” 514.

As another example, controlling data usage may include detecting a use purpose of tethered data. The controller 110 of the mobile device 100 may detect a use purpose of tethered data, and adjust an amount of data that is to be tethered to correspond to each of at least one leecher, according to the use purpose of the tethered data. For example, a use purpose of tethered data with respect to a first leecher may be execution of an application, such as web browsing, a cloud backup application, or company E-mail. If importance of web browsing has been set to a low level, the controller 110 may decrease an amount of data that is to be tethered with respect to a first leecher using the web browsing. Meanwhile, if importance of company E-mail has been set to a high level, the controller 110 may increase an amount of data that is to be tethered with respect to a first leecher using company E-mail. As such, the controller 110 may detect a use purpose of tethered data, and decrease or increase an amount of data that is to be tethered to correspond to each of at least one leecher, according to the use purpose of the tethered data. Also, the controller 110 may display the use purpose of the tethered data on the display unit 190. For example, as illustrated in FIG. 6, the controller 110 may display a use purpose of tethered data corresponding to a first leecher as “Web browsing” 517 or “Dropbox” 516.

As another example, controlling data usage may include adjusting a maximum data limit that can be tethered to each of at least one leecher. The controller 110 of the mobile device 100 may adjust a maximum data limit that can be tethered to each of at least one leecher. For example, the controller 110 may increase or decrease a maximum data limit that can be tethered to a first leecher. Also, the controller 110 may display a maximum data limit that can be tethered to a first leecher on the display unit 190. For example, as illustrated in FIG. 6, the controller 110 may display a maximum data limit that can be tethered to correspond to a first leecher, as “200 MB” 513, on the display unit 190. Also, the controller 110 may display an unused amount of data resulting from subtracting the amount of tethered data from the maximum data limit. For example, as illustrated in FIG. 6, the controller 110 may display an unused amount of data of 108 MB 515 resulting from subtracting the amount of tethered data of 92 MB 514 from the maximum data limit of 200 MB 513. In addition, the controller 110 may display an “Adjust limit” icon 519 for adjusting the maximum data limit that can be tethered to each of the at least one leecher. As another example, controlling data usage may include monitoring an amount of data tethered to each of the at least one leecher in real time to re-adjust the maximum data limit. The controller 110 of the mobile device 100 may monitor an amount of data tethered to each of the at least one leecher in real time to re-adjust the maximum data limit. For example, if an amount of data tethered to a first leecher is monitored to be 92 MB, the controller 110 may re-adjust the maximum data limit from 200 MB to 300 MB. Specifically, the controller 110 may re-adjust the maximum data limit in consideration of an amount of data tethered to each of the at least one leecher and monitored in real time.

As another example, controlling data usage may include stopping tethering with respect to each of the at least one leecher. The controller 110 of the mobile device 100 may stop tethering with respect to each of the at least one leecher. For example, the controller 110 may stop tethering with respect to the first leecher. At this time, the controller 110 may display a “Disconnect” icon 518 for stopping tethering, and when the “Disconnect” icon 518 is selected, the controller 110 may stop tethering with respect to the first leecher.

As another example, controlling data usage may include accepting a request for tethering additional data exceeding the maximum data limit from the at least one leecher. The controller 110 of the mobile device 100 may determine whether a request for tethering additional data exceeding the maximum data limit from the at least one leecher has been accepted, and adjust an amount of data that is to be tethered to correspond to the at least one leecher, according to the result of the determination. For example, if the controller 110 determines that a request for tethering additional data exceeding the maximum data limit from the at least one leecher has been accepted, the controller 110 may increase an amount of data that is tethered to correspond to each of the at least one leecher. Meanwhile, if the controller 110 determines that a request for tethering additional data exceeding the maximum data limit from the at least one leecher has not been accepted, the controller 110 may maintain an amount of data that is to be tethered to correspond to each of the at least one leecher.

FIG. 8 is a flowchart illustrating a tethering distribution control method, according to another embodiment of the present invention. Steps 1210 and 1220 of FIG. 8 are substantially identical to steps 1110 and 1120 of FIG. 4.

Referring to FIGS. 1 and 8, at least one leecher, to which data is to be tethered, may be detected, in step 1210.

Characteristics of the at least one leecher may be detected, in step 1212. The controller 110 may detect characteristic of the at least one leecher. For example, the characteristics of the at least one leecher may include at least one of a device type, user information, and a number of leechers. For example, the controller 110 may detect a tablet PC as the device type, “me” as the user information, and 3 as the number of leechers. Also, the controller 110 may display the characteristics of the at least one leecher on the display unit 190. For example, as illustrated in FIG. 6, the controller 110 may display “Galaxy Tab 10.1 SWON” 511 as the device type, “Me (Steve Won)” 512 as the user information, and “3” 420 as the number of leechers.

Thereafter, a previous pattern of data tethered to correspond to each of the at least one leecher may be detected, in step 1214. The controller 110 may detect a previous pattern of data tethered to correspond to each of the at least one leecher. For example, a previous pattern of tethered data may include a previously used application and data usage corresponding to the application. For example, a previous pattern of tethered data may include a web browsing application and data usage of 50 MB. As such, the controller 110 may detect a previous pattern of data tethered to correspond to each of the at least one leecher.

An amount or kind of data that is to be tethered may be recommended in consideration of characteristics of the at least one leecher or a previous pattern of tethered data, in step 1216. The controller 110 may recommend an amount or kind of data that is to be tethered, in consideration of characteristics of the at least one leecher, or a previous pattern of tethered data.

For example, the controller 110 may recommend an amount or kind of data that is to be tethered, in consideration of characteristics of the at least one leecher. For example, the controller 110 may recommend an amount or kind of data that is to be tethered, in consideration of characteristics of the at least one leecher, such as a device type. If the user information is “me”, the controller 110 may recommend a large amount of data. If the user information is an unknown person, the controller 110 may recommend a small amount of data.

As another example, the controller 110 may increase or decrease an amount of data that is to be tethered, based on the number of the at least one leecher. For example, if a first leecher has been connected, the controller 110 may recommend 1 GB to a second leecher, and if the second leecher has been connected, the controller 110 may recommend 750 MB to a third leecher, in correspondence to the number of the at least one leecher. Specifically, the controller 110 may increase or decrease an amount of data that is to be tethered, gradually, in correspondence to the number of connected leechers.

As another example, the controller 110 may recommend an amount or kind of data that is to be tethered, in consideration of a previous pattern of tethered data. Specifically, if a previous pattern of tethered data is data usage of 50 MB for a web browsing application, the controller 110 may recommend an amount or kind of data that is to be tethered, in consideration of the web browsing application and the data usage of 50 MB. For example, the controller 110 may recommend the web browsing application for data usage of 60 MB that is larger than 50 MB, as an amount and kind of data that is to be tethered. As another example, if a previous pattern of tethered data is average data usage of 10 MB per one session for “me”, the controller 110 may recommend average data usage of 10 MB for “me”.

Data that is to be tethered to the at least one leecher may be controlled according to the recommended amount or kind of data that is to be tethered, in step 1220. The controller 110 of the mobile device 100 may control data that is to be tethered to the at least one leecher, according to the recommended amount or kind of data that is to be tethered. Controlling data that is to be tethered may include controlling data usage by adjusting an amount of data that is to be tethered to correspond to each of the at least one leecher. Accordingly, the controller 110 may control data usage by adjusting an amount of data that is to be tethered to correspond to each of the at least one leecher, according to the recommended amount or kind of data that is to be tethered.

As such, in a tethering distribution control method, according to another embodiment of the present invention, an amount or kind of data that is to be tethered can be recommended in consideration of characteristics of at least one leecher or a previous pattern of tethered data.

Referring again to FIGS. 1 and 4, a tethering distribution control method according to another embodiment of the present invention is described in detail below.

At least one leecher to which data is to be tethered may be detected, in step 1110. The controller 110 of the mobile device 100 may detect at least one leecher to which data is to be tethered.

Data that is to be tethered to the at least one leecher may be controlled, in step 1120. The controller 110 of the mobile device 100 may control data that is to be tethered to the at least one leecher. Controlling the data may include controlling data usage by adjusting an amount of data that is to be tethered to correspond to each of the at least one leecher.

Controlling data usage may include controlling data usage based on a maximum data limit usable according to a data network plan. The data network plan may be a plan about a data amount able to be provided by a communication company connected to the mobile device 100. For example, if a data amount able to be provided by the communication company connected to the mobile device 100 is 5 GB, the controller 110 may display that data amount as “5 GB” 410, as illustrated in FIGS. 6 and 7. Mobile device may display the amount of usage data of 14 GB 412.

Controlling the maximum data limit may include adjusting a ratio of an amount of data that is to be tethered with respect to the maximum data limit. Specifically, the controller 110 may control data usage by adjusting an amount of data that is to be tethered to correspond to each of the at least one leecher, in such a manner as to adjust a ratio of an amount of data that is to be tethered with respect to the maximum data limit. The controller 110 may display a ratio of an amount of data that is to be tethered with respect to the maximum data limit on the display unit 610, as shown by reference numeral 610 of FIG. 7.

The controller 110 may set a ratio of an amount of data that is to be tethered, with respect to the maximum data limit, to 80%. If the maximum data limit is 5 GB, an amount of data that is to be tethered is 4 GB. The controller 110 may display the ratio of 80% as an “80% of overall data plan” icon 612, as illustrated in FIG. 7. Also, the controller 110 may adjust a ratio of an amount of data that is to be tethered with respect to the maximum data limit, using a ratio of a leftover data amount with respect to the maximum data limit (an “80% of leftover data plan” icon 614 of FIG. 7). Also, controlling the maximum data limit may include adjusting an amount of data that is to be tethered to a predetermined amount of data (“3.0 GB” icon 616 of FIG. 7), or not adjusting an amount of data that is to be tethered (“None” icon 618 of FIG. 7).

As another example, controlling the maximum data limit may include allowing tethering of additional data exceeding the maximum data limit. The controller 110 may adjust an amount of data that is to be tethered to correspond to each of the at least one leecher by allowing tethering of additional data exceeding the maximum data limit. Accordingly, if tethering of additional data exceeding the maximum data limit is allowed, the controller 110 may limitlessly allow an amount of data that is to be tethered to correspond to each of the at least one leecher. The controller 110 may receive a request for tethering additional data exceeding the maximum data limit, from the at least one leecher. Then, the controller 110 may display icons for accepting or rejecting the request, as shown in 640 of FIG. 7. The icons may include an “Always” icon 642, an “Ask per device” icon 644, and a “Never” icon 646. If the “Always” icon 642 or the “Ask per device” icon 644 is selected, the controller 110 may allow tethering of additional data exceeding the maximum data limit, using an option item “More options” 532 in FIG. 6. If tethering of additional data exceeding the maximum data limit (536) is disallowed, the controller 110 may limit an amount of data that is to be tethered to correspond to each of the at least one leecher. As illustrated in FIG. 6, if the controller 110 determines that a “Block this device from exceeding may data plan” icon 534 for disallowing tethering of additional data exceeding the maximum data limit has been selected, the controller 110 may disallow tethering of additional data exceeding the maximum data limit.

Therefore, in the tethering distribution control method, according to this other embodiment of the present invention, by adjusting a ratio of an amount of data that is to be tethered with respect to a maximum data limit, or allowing tethering of additional data exceeding the maximum data limit, it is possible to adjust an amount of data that is to be tethered to correspond to the at least one leecher.

FIG. 9 is a flowchart illustrating a tethering distribution control method, according to another embodiment of the present invention. Steps 1310 and 1320 of FIG. 9 are substantially identical to steps 1110 and 1120 of FIG. 4.

Referring to FIGS. 1 and 9, at least one leecher to which data is to be tethered may be detected, in step 1310. The controller 110 of the mobile device 100 may detect at least one leecher to which data is to be tethered.

It is determined whether an agreement on giving and taking the tethered data is received from at least one leecher, in step 1312. The controller 110 may receive an agreement on giving and taking the tethered data from the at least one leecher. The agreement on giving and taking the tethered data may include an expiration period.

As another example, a central mediator may receive an agreement on giving and taking tethered data from the at least one leecher. The central mediator may be a server having accounts of the mobile device 100 and the at least one leecher. The central mediator may recognize an amount and kind of data that is tethered between the mobile device 100 and the at least one leecher.

The controller 110 may display an “Always” icon 632 for always allowing a function of giving and taking tethered data, an “Ask per device” icon 634 for asking each leecher about whether to allow the function of giving and taking tethered data, and a “Never” icon 636 for disallowing the function of giving and taking tethered data, as illustrated in 630 of FIG. 7, and enable a user to select one of the “Always”, “Ask per device” and “Never” icons 632, 634, and 636.

FIGS. 10A, 10B, and 10C show screens on which the tethering distribution control method, according to an embodiment of the present invention, is executed. Referring to FIGS. 1 and 10A, at least one leecher may detect a mobile hotspot “Steve's Galaxy Note” 720, and display the mobile hotspot “Steve's Galaxy Note” 720 on the display unit 190. For example the mobile device may be connected to the at least one of the leecher by WI-FI 710.

Thereafter, if the at least one leecher determines that the mobile hotspot “Steve's Galaxy Note” 720 has been selected 722, the at least one leecher may display a notice message 730 including an “Agree” icon 734 and a “Cancel” icon 736 to ask about whether to agree 732 on giving and taking tethered data, text 732 that may be indicated the notice message as illustrated in FIG. 10B. If the “Agree” icon 734 is selected, the at least one leecher may transmit an agree message to a mobile device corresponding to the mobile hotspot “Steve's Galaxy Note” 720. A controller (e.g., the controller 110 of FIG. 1) of a mobile device (e.g, the mobile device 100 of FIG. 1) corresponding to the mobile hotspot “Steve's Galaxy Note” 720 may receive an agreement on giving and taking tethered data from the at least one leecher. If no agreement on giving and taking tethering data is received or if a cancel message is received, the process terminates.

Referring back to FIG. 9, if an agreement on giving and taking tethering data is not received, the methodology terminates. If an agreement on giving and taking tethering data is received, tethering with respect to the at least one leecher may be performed, in step 1314. The at least one leecher may display information notifying that tethering has starts on a display unit, as illustrated in 740 of FIG. 10C. The controller 110 of the mobile device 100 may display an icon 522 representing an agreement corresponding to the at least one leecher, as illustrated in FIG. 6.

Data that is to be tethered to the at least one leecher may be controlled, in step 1320. The controller 110 of the mobile device 100 may control data that is to be tethered to the at least one leecher. Controlling the data may include controlling data usage by adjusting an amount of data that is to be tethered to correspond to the at least one leecher.

Tethered data may be given and taken to and from the at least one leecher, in step 1330. The controller 110 of the mobile device 100 may give and take tethered data to and from the at least one leecher. For example, if an amount of data which the mobile device 100 has tethered to the at least one leecher is 2 GB, the controller 110 of the mobile device 100 may give and take the tethered data of 2 GB to and from the at least one leecher. At this time, the controller 110 of the mobile device 100 may send a request 810 for giving and taking the tethered data to the at least one leecher.

FIGS. 11A and 11B shows screens on which the tethering distribution control method is executed, according to another embodiment of the present invention. The at least one leecher, which has received a request 810 for giving and taking the tethered data may display the request 810 and text 812 that indicated the request 810 on a display unit, as illustrated in FIG. 11B. The at least one leecher may display an “Accept” icon 814, an “Adjust setting” icon 816, and a “Reject” icon 818 for responding to the request 810, on the display unit. If the “Accept” icon 814 is selected, the mobile device 100 may give and take the tethered data to and from the at least one leecher.

As another example, a central mediator may receive a request for giving and taking tethered data to and from the at least one leecher, from the mobile device 100, and transfer the request to the at least one leecher. The central mediator may recognize data tethered to the at least one leecher from the mobile device 100, and take the overall control of giving and taking the tethered data.

Therefore, in the tethering distribution control method, according to an embodiment of the present invention, tethered data can be given and taken to and from at least one leecher.

Hereinafter, a tethering distribution control method, according to another embodiment of the present invention, is described with reference to FIG. 4.

Referring again to FIGS. 1 and 4, at least one leecher to which data is to be tethered may be detected, in step 1110. The controller 110 of the mobile device 100 may detect at least one leecher to which data is to be tethered.

Data that is to be tethered to the at least one leecher may be controlled, in step 1120. The controller 110 of the mobile device 100 may control data that is to be tethered to the at least one leecher. The controlling of the data may include controlling data usage by adjusting an amount of data that is to be tethered to correspond to the at least one leecher.

Controlling data usage may include controlling data usage based on priority according to at least one of a use purpose of tethered data, user information, whether a currently used application is a downloaded application, whether to agree on giving and taking tethered data, and communication quality. The priority may have been decided in advance by a user.

For example, the priority may be decided according to a use purpose of tethered data. The use purpose of tethered data may be video streams, music streams, web browsing, personal E-mail, or company E-mail. The priority may be decided according to such a use purpose of tethered data. Use purposes of tethered data may be grouped into one or more categories. The controller 110 may decide priority according to a use purpose of tethered data, and adjust an amount of data that is to be tethered to correspond to each of the at least one leecher, according to the priority. For example, if company E-mail has been decided to have highest priority, the controller 110 may assign a more amount of data to company E-mail than to video streams.

As another example, the priority may be decided according to user information.

If the user information is “me”, the controller 110 may increase an amount of tethered data corresponding to at least one leecher of “me”.

As another example, the priority may be decided according to whether a currently used application is a downloaded application. The controller 110 may assign a lower priority to downloaded applications, and a higher priority to native applications. Accordingly, the controller 110 may decrease an amount of data that is to be tethered to correspond to a downloaded application, and increase an amount of data that is to be tethered to correspond to a native application.

As another example, the priority may be decided according to whether an agreement has been made on giving and taking tethered data. If an agreement on giving and taking tethered data is received, as described above with reference to FIG. 9, the controller 110 may increase priority. Accordingly, the controller 110 may increase an amount of data that is to be tethered to correspond to the least one leecher from which the agreement on giving and taking tethered data has been received.

As another example, the priority may be decided according to connection status. The connection status may be between the mobile device 100 and at least one leecher. If a connection status between the at least one leecher and the mobile device 100 is in a good condition, the controller 110 may increase priority. Accordingly, the controller 110 may increase an amount of data that is to be tethered to correspond to at least one leecher that is in a good connection status with the mobile device.

Accordingly, in the tethering distribution control method it is possible to adjust an amount of data that is to be tethered to correspond to at least one leecher according to a priority.

Therefore, as described above, according to a tethering distribution control method of an embodiment of the present invention, it is possible to adjust an amount of data that is to be tethered to correspond to each of at least one leecher.

According to a tethering distribution control method of another embodiment of the present invention, it is possible to recommend an amount or kind of data that is to be tethered, in consideration of characteristics of at least one leecher or a previous pattern of tethered data.

According to a tethering distribution control method of another embodiment of the present invention, it is possible to give and take tethered data to and from at least one leecher.
